I will start by saying, I have visited Northfield and Carleton, and I have done a lot of reading about the school. I would not say that I am an expert though. The best thing that you can do is look on the web for students that have discussed their experiences. I will tell you my impressions. It’s a top academic school. extremely rigorous without the competition that you find at some of the academically comparable schools on the east coast.I believe that it has inherited much of the midwestern friendliness.
There is another college in the town, St. Olaf, and I understand that there is mingling that goes on between the schools, though I don’t know the mechanism that allows that. There is not much to do in the town, but Carleton has a lot of events on campus such as concerts and movies to help prevent boredom. There are also many clubs on campus to allow the students to be active in areas of interest.
The school is very liberal and has a strong activist bent to it, but it is tolerant of other beliefs. When we interviewed, we had a wonderful interviewer, and we discussed this. As it turned out, she was actually fairly religious and on the conservative side, but still felt welcomed on campus.
The students are often defined as being quirky. I have a feel for what that is, but it’s a little hard to describe. Does that mean nerdy but with a good sense of humor, perhaps that’s part of it. The diversity can be found pretty easily, just google it and it will come up. There are places that have that information readily available. One excellent source of data is the Common Data Set.
As I think of more things to add, I will. Pros: Strong academics, friendly, very pretty, Cons: It will be too remote for some people. The town is small, and so is the school. Neutral depending on your personal taste: the quirkiness.
My son has been accepted, and desperately wants to go there. It is his first choice. We have some better financial offers on the table that we will have to investigate a little more,but he fell in love with it. He is very intense, good student, but looking for something that is collaborative.
I hope that helps. Good luck.
